Contact: Qi Shuo; Tel: 18332463496; QQ: 3260520587 grounding wire grounding line is the line directly connected to the earth, may also be called safe return line, it took the risk of high-voltage direct onto the Earth, considered a lifeline. Due to poor insulation household appliances or humid environment, it will lead to its shell with a certain static, and in severe danger of electric shock. In order to avoid an accident may be connected a wire in the electrical metal housing above the other end of the wire to earth, in the event of electrical leakage occurs static grounding line will bring to the land released. In addition to electrical maintenance personnel in the use of electric iron soldering circuit, sometimes because of a charged electric iron and damage to electrical breakdown of integrated circuits, which is more important. The use of computer friends sometimes ignore host shell ground, in fact, connected to the host computer shell ground wire, to a certain extent, can prevent the phenomenon of death. In the power system grounding line: an important tool in order to have power outages when equipment and line voltage appears unexpectedly assurance staff. According to the ministerial regulations, ground must be more than 25mm 2 bare copper cord made. Profile appliances, ground wire is connected to the electrical equipment housing and other parts in a timely manner will be due to various causes of insecurity charge or leakage current export routes. (1) high-voltage ground wire effect: high voltage lines and ground lines are used for substation construction, in order to prevent near the charged body to ensure the safety of the use or misuse of electrostatic induction shock when closing. (2) high-voltage ground wire structure: carry-pressure ground wire from the insulated operating rod, wire clips, short routes, grounding wire, grounding terminals, bus clip, earth clamp. (3) A ground wire production process: the production process fine - wire clip, earth clamp is made of high quality aluminum die casting; operating rod tube with epoxy resin color, good insulation properties, high strength, light weight, bright appearance smooth; grounding quality multi-strand soft copper soft copper twisted together and covered with soft, transparent high-temperature insulating sheath can prevent the use of wear and tear on the ground copper wire, copper wire fatigue testing requirements, ensure worker safety in operation. (4) Grounding Specifications: according to the ministerial regulations, ground must be more than 25mm 2 bare copper cord made. Resistance requirements: High short-circuit ground wire to ground resistance requirements determine the quality of the ground wire, generally in accordance with the power industry DL-T879-2004 technical requirements of each cross-sectional area of ??the ground wire to ground resistance is not greater than the following values: between lugs DC resistance measurement, for 16mm2, various cross-sectional 25mm2,35mm2,50mm2,70mm2,95mm2,120mm2 average per meter resistance should be less than respectively 1.24mΩ, 0.79mΩ, 0.56mΩ, 0.40mΩ, 0.28mΩ, 0.21mΩ, 0.16mΩ. High-voltage ground wire Classification (1) the use of high-voltage ground wire in accordance with the environment can be divided into: indoor busbar grounding line (JDX-NL) and outdoor circuit-type ground wire (JDX-WS). (2) high-voltage ground wire in accordance with the voltage level can be divided into: 10KV ground wire, 35KV high-voltage ground wire, 110KV grounding line, 220KV high-voltage ground wire, 500KV high-voltage ground wire technical parameters (1) 10KV high-voltage ground wire insulated rod section length: 700 Handshake Part mm Length: 300 mm metal joint portion length: 50 mm Sessions: 1 Path: 30mm total length (excluding clip): 1050 mm (2) 35KV ground wire nominal cross section: 25mm2 total root number: 810 Average diameter (mm): 0.2mm calculated cross-section: (mm2): 25.43 metal joint portion length: 50 mm Sessions: 1 Diameter: 30mm (3) 110KV high-voltage ground wire nominal cross section: 35mm2 total root number: 1136 average diameter (mm ): 0.2mm calculated cross-section: (mm2): 35.67 parts of insulating rod length: 1360 mm Handshake part of the length: 700 mm metal joint portion length: 140 mm Sessions: 2 Diameter: 30mm total length (excluding clip): 2200 mm When you use Description (1) Articulated ground: first connecting grounding clip, followed by electrical connection clip; when removing the grounding line, the program must first disconnect Clips, after the demolition earth clamp. (2) Installation: on the ground soft copper phase copper nose, eyes fixed on the ground rod grounding Clips (Continued Clips fixed and movable type) corresponding position on the unilateral copper nose on the ground Conjunction fixed on the ground folder or needle, constitute a complete grounding wire. (3) Verify that the voltage level and the ground rod operation of the device are the same voltage level. (4) took part in the ground soft copper phase and modular, ground rods have flat type and double reed hook clamp. Maintenance use portable short-circuit ground wire before, should confirm a priori power outage, make sure no voltage on the device after. First grounding clamp is connected to the grounding grid or flat iron, then stick with the ground operation will lead each class end line and tighten the wires on the device. When removing the short-circuit ground wire, just above the opposite order. Installation of a short-circuit ground wire from it and live equipment, taking into account the impact of the grounding wire pendulum, the safety distance should be no less than the value of the new regulations, "electrical safety work order." And use non-wrapping method is shorted to ground without clamp. If the suspension point ground, apply grounding clamp or special rod for its ground connection; if no fixed ground available; you can use a temporary grounding point, grounding buried depth should not be less than 0.6m. Portable short-circuit ground wire should be properly kept. Before each use, should carefully check whether it is intact, no to bare copper wire, nut is not loose, shall be used. Portable short-circuit ground wire test cycles once every five years, with factory inspection test items. After passing the test of portable short-circuit ground wire after being subjected to a short circuit, should be based on the size and appearance to withstand short-circuit current test judgment, the general should be scrapped fine ground wire, high-quality short-circuit ground wire, ground wire standard high-voltage, short circuit grounding wire manufacturers, 10KV ground wire, 110kv ground wire, 220kv high-voltage ground wire, 35KV portable short-circuit ground wire, of personal security, grounding rods, high-voltage ground rods, Low ground rods, ground wire high-voltage, low-voltage ground wire, 110kv high-voltage circuit ground wire, grounding spiral bar, two-man ground rods, ground wire indoor and outdoor grounding line, 110KV portable short-circuit ground wire lessons learned over the years of production, with more than 10 years to serve at all levels of the power system (power companies, power plants, industrial and mining enterprises, oil, coal other units) to provide actual product under different voltage levels and different use of the environment required to summarize the classification of products. Short-circuit ground wire Categories: different voltage levels, the specific configuration of different use environments are different, the specific configuration of the same voltage level different environments are different (the length of ground rods, electrical connection clip style, soft copper grounding thickness, length, grounding wire, etc.). Therefore, the user must be clarified in the purchase of specific environments and accurate voltage levels, in order to correct selection. This is our Power Tools Co., Ltd. Hebei Li Tak classification selection basis. According to different voltage levels can be divided into 380V, 6KV, 10KV, 35KV, 66KV, 110KV, 220KV, 330KV and 500KV.
